lain new and useful Inkiug Devious for Printinglrosses. of which tho following is a sp-e itioation.

This lllVilIllZlOIl rolatrs to devices tor at plying); int: to rollers of printing presses and similar devices.

The object is to provide an accurate teed of the ink film on the roller making it possilole to adjust the thickness of tho'inlc without interrupting the operation of the device.

A tru'ther object is to simplify the mochanisni and improve the ocljustability thereof.

Tlhoso and further objects will more fully appear from the following specification and accompanying drawings, considered together or soparatoly.

in the drawings, Figure '1 a roar ole'va eion of an inl: reservoir and the supports thorotor. showing one embodimei'itof tho invention applied theroto. Fig. 2 is a scotion on tho lino E2--2 of Fig. 1, on an enlarged scale. Fig. 3 is asoctiou on tho lino 3 55 oi liig. 72:, and Fig. 4: is a diagrammatic View of tho re... :rro'ir and inking rollers, and l igz. 5 is a view of a modification.

lo all of the views, like parts are designatod by tho same reference characters.

In the omln'nliinont chosen. for illustratimi, tho ink reservoir 1 has an inclined bottom 55. this inclined hottoin ills combined with tho hass 3. This has. is preferably a ousting, ouulo o'l sullioiont size and strength to adequutoly support. tho r-"sorroir. In addition to tho hast. tho bottom iscomposod of a flexihlo plats t. This plate is shown as attached in position by means of bolts 19. Ono side it tin-2 rs. rvoir' is closed by a. roller 5. ()r lll'uli'lljf, tho roller does not room into hunol. contact with, tho .lloxihlo plate, but a rat moo ll is loll. between tho plate and the loll er.

as by the bolts 8. llohiud tho plate 7 is a reco 1; 9. In this roooss l) is a row of balls 10*. Any kind oi hulls "may be used, but I profor to uso haidomid stool balls. These balls uro closely arranged sido by side. and in Contact; with oat-h other. They bear against tho lower side of tho lloxiblo plate l. The halls rest upon oyliiulrical hlorlis ll. In tho oi'nhotliwont chosen for illustration, each hlook engages with two balls. Each block is provided with a grohvo 12, protorably lo mated at about tho huddle of tho block hstwoou tho ba ls, as shown. A conical point (all scrowthroadod bolt 11:3 engages with the groove 12. Thoro are, of course, as many bolls as thoro are blocks, and twico as many balls as blot-ks. Thoso bolts pass through the oaso 25, and each is provided with an operating head ll. Those bolts support the halls. .ln tho (embodiment chosen for illustration, and shown in Figs. 1 to 23, inclusive, tho bolts support the halls through the intermediary of the liloolts. In another form of the invention, to he desrrilu-ul horoinal'ter, tho bolts support the halls by direct engago mont. The bolts therefms constitute manually actuated adjusting; dovit-os for the balls. ln order to group tho bolts as closely possible and at the same time to allow room to turn tho hoods thereof, their positions are preferably staggered, as shown in Figs. 1 and 2. it is apparent that by long'i tudinally moving; Cilkfll bolt. by rotating the Smuu. that tho tip of the bolt engaging with the groom- 12 will raise or lowor'tho block 11, and will move the halls which engage with such block. The: tuovoinont of tho halls will flex the plate at and move it toymrtl the roller. and thus vary the width. of the space l) and the oonscquent thickness oi. the. ink film. It is appzu'out that the halls support tho plots at close intervals, and as tivo halls aro actuated hy ono bolt, it is apparent that onl t oils-hall? us n'muy bolts are nooossar as thorn aro points of oontaot with the p ate. Tins permits a very lino adjustment and st tho same time gives adequate and close support for tho :h'oo end of tho lloxihlo plate. Ht otoloro, tho flexible plato has been dirootly mu aguul by bolts; hours, in ordor to have as closo spacing of tho luttor, thoir hhads have. to ho mado inoonvenioutly small. Await-drug to my IITVOTIlLQI l not may have largo hoods on the holtsfhut only According to my invention, the plate 4; is

directly moved by the engagement of the balls 10, hence I will denominate them in the following claims as the moving devices. These balls are engaged by the blocks 11, which I therefore term the intermediate devices. These blocks, in turn, are moved by means of the bolts 13 which are manually manipulated, a hence I will refer to them as the actuating devices.

I have illustrated my invention in connection with a structure in which the plate 4 is moved by the direct action of a series of closely assembled balls. lit is to be understood that, in lieu of balls, moving devices "of different shape may be employed. In the embodiment chosen for illustration, l have shown the blocks 11 as cylindrical, but it is to be understood that the intermediate devices may be of 'didere'nt shape than those shown. So also the actuating devices may be difierent.

The plate 7 is provided with a ledge 7,

extending the full length of the recess This ledge will act as a support for the rollers 11, when the bolts 13 are withdrawn and the rollers will be retained .in the proper position to receive the points of the bolts when they are returned to their places.

My invention may be carried out in an apparatus wherein the intermediate devices are omitted and only the .moving devices and actuating devices are used. Such a device is shown in Fig. 5, wherein the bolts 13 are shown as each engagingv directly with a pair of balls 10, which, in turn, support the edge of'the flexible plate 4..

In accordance with the provisions of the patent statutes, 1 have described the principle of my invention, together with the apparatus which l now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus .shown is merely illustrative and that the invention can be carried out in other ways.
